Title

DENSITY!!!

Introduction
We have been doing a lot of different things in science. so many that i cannot even name them all! The thing that I am testing is density and how fast it takes different liquids to seperate after mixed for 5 seconds. I did this project because it gave me a reason to use food coloring and see how different liquids mix. I started out testing how long it would take for the liquids to seperate after mixed for one minute and then once i actually tested it i realized it only took five seconds to mix everything. The independent variable is the different liquids and the dependent variable is the time.

I. Hypothesis
I predict that it will take about a minute for the liquids to seperate. I also predict that water will be the most dense except for the juice. i have seen things that were mixed together like lava lamps and others and i predict that it would not act like a lava lamp because the liquids wont be held together like in a lava lamp.
II. Materials and Methods
to do this project i had to get vegetable oil, apple juice, and orange juice. Since i already have water the only other thing tat i needed to buy was food coloring so that i could tell what liquids were mixed. what i did was take all of the different things and laid them out on the table and then got the five containers and put the liquids in. then i mixed everything and recorded how long it took for each of them to seperate.
III. Results
After i mixed each of the liquids and recorded the times i found out this
Liquids Mixed Together
Color
Time

water+ vegetable oil
green
45 seconds

water+ apple juice

water+ vinager

vegitable oil+ vinager
blue
45 seconds

vegitable oil+ apple juice
orange
45 seconds






  • means that the two liquids did not separate


IV. Conclusion
i conclude that when i mix any liquid with vegetable oil, it will seperate. in the end it took 45 scond for the liquids to seperate which was much quicker than i expected. so i conclude that the vegetable oil is the least dense.
V. Explanation
The vegetable oil was the least dense out of every liquid that I mixed. Also the water, vinegar, and juices had the sma densities.
